Traditional cyber-security methods are inadequate to address the increasing number of threats within larger and higher-performance networks. The U.S. Computer Emergency Readiness Team (US-CERT), the National Institute of Standards and Technology (NIST), the Department of Energy (DOE) Office of the… More

High performance network users are frequently unable to achieve adequate throughput when transferring large files across wide-area networks. In general, such poor file transfer performance over ¿long fat networks¿ (LFN) is primarily caused by limitations in transport protocols and network stack… More

There is a need for improved collaboration between and within groups of network operators and users. At present, a variety of tools exist to share network health and status between domains, reserve resources across multiple networks, and remotely access computing and storage resources. However, no… More

In order to enable the efficient use of high performance networks, the DOE has invested substantial resources in the development of next-generation network provisioning systems. For example, the DOE-funded tool, On-demand Secure Circuits and Advanced Reservation System (OSCARS), enables users to… More

Development of 100 Gb/s network infrastructure, even though nascent, is gathering momentum as a result of the progress made in the 100 Gb/s Ethernet and Optical Transport Network (OTN) standardization efforts. A 100 Gb/s test bed proposed by ESNet is expected to facilitate rapid data transfer… More

Traditional enterprise cyber-security methods are inadequate to address the increasing number of threats, particularly within larger and higher-performance networks. Several government and third party organizations report consistent failures within corporate and federal, state, and local government… More
